25, 1919. Serial No. 273,185. r

This invention relates to typewritermani-' folding by the use of webs,and, in certain respects, hereinafter set forth is in the nature of animprovement on the fan-fold web shown in the \Vernery and Smith Patent,No. 1,132,055. As in the case of the fanfold web, one object of thepresent inven- .tion is to prevent the creeping of the web plies as theyare fed about the platen of a typewriter.

The fan-fold web is relatively slow and expensive to manufacture.Moreover, the cost of the material is prohibitive in many instances,'for the reason that where an extra fine quality of rather heavy paperis desired for the original copy, that is, for the outermost ply, it isnecessary to use the same expensive grade of paper for all .theremaining plies, of which there may be as many as six or more. Expensivepaper is not needed for such remaining plies, which are merely carboncopies and merely intended for employees assistance. Moreover, thecarbon copies are not clear where so many plies of expensive heavy paperare used. Owing,

therefore, to the item of the paper cost and the lack ofclearness of thecarbon copies, the field for fan-fold machines has heretofore beenlimited to a cheap class of work, using inexpensive and thin paper.Moreover, all

of the plies are of the same color, so that the expedient, which isfavored in many offices, of havingdifferent copies made on differentcolors of paper, cannot be adopted.

The principal object of my invention,

therefore, is to enable an economy to be effectedin the cost of thepaper, and tosscure clean carbon copies, without resorting to thenecessity of supplying difierent qualities of paper from differentspools to the typewriting machine, with its'attendant liability ofcreeping and disalinement of the forms on the different plies, and alsoto per-.

mit the use of different colors or qualities of paper in the assemblage.In other words,

the object of myinvention is to preserve all the advanages that accruefrom supplying the webs from separate spools simultaneously to thetypewriting machine, and at the same time preserve all of the advantagesaccruing from the use of a fan-fold web, while le)lin}i1inating theprincipal disadvantages of Other features and advantages willhereinafter appear.

In the accompanying drawings, Figure 1 is a diagram of'means for printmgthe separate original webs each upon both sides so that the formswillall correspond, means for applying adhesive material (or otherwiseproviding for adhesion of superposed webs) to the webs along the foldline, which is usually about central of the web, means for assemblingthe printed and adhering webs '(the adhesion may be omitted in manycases), means for perforating theassembled webs longitudinally andcentrally at the line of the subsequent fold, means for folding theassembled webs to make a single multiple-ply web, and means for kzigzagcross-folding the. webto make a pac I Fig. 2 is a perspective diagram ofa web pack, showing theregistering forms printed upon the various pliesthereof, and show-' -Feb.'17, 1920,) disclosing the above described webpack and means for producing the same. Although the means for producingsaid pack has been illustrated and described herein,

' in order that the disclosure of the product may be adequately setforth, the claims for saidmeans have been retained in said priorapplication, the claims of this divisional application being confined tothe product.

In place of the web spools and the fanfold web, I employ a multiplex webcomprising two main elements, the first of which 1917, Serial No.197,373. Divided and this application filed ianuary is a container 10,and the second of which is a web or webs 11, 12 within the container;

' the whole being cross-folded back and forth as' at 13 to form aconvenient package 1d through the printing couples 18, 19, 20, 21,

. tudinally at 24* by perforating means 25..

22, 23, are brought to an assembled condition one upon another at 24:,and preferably each web is then perforated centrally long1- The web isthen led to a V-shaped or other suitable folding device 26, whichlongitudlnally folds the assembled webs into one multiple web. This thenpasses to a cross-folder at 26*, which zigzags or makes back and forthfolds in the web to reduce it to convenient package form at 27.

The outer folded element 10 of the mul- 'tiple web performs theimportant function of a container for the other elements, holding thesame against relative endwise displacement, and may be made, whendesired, of much' higher grade paper than the inner plies. Said innerplies 11, 12 are also folded and lie snugly within the fold of thecontainer, and are held thereby and by one another against relativecreeping among the webs; the friction of the contacting web surfacesupon one another at and near the folded margin being sufficient toprevent such creeping as the unit passes through the typewritingmachine. The inner websmay be of cheap paper, and each web may becolored differently from the others, 11 and 12 being shown asdifferently colored from each other and from the container 10.

When desired, a modicum of adhesive material may be applied by tootheddevices 28 at intervals at the fold lines of the inner webs, to holdthem to one another and to the container even more securely against thepossibility of relative creeping; although the adhesive material (orother tacking device) may be dispensed with in many cases, as thepossibility of creeping is practically eliminated by the describedexpedient of having the inner webs folded snugly one within the otherand both within the fold of the container web. Moreover, the fact thatthe webs are folded back and forth in the final package precludes anypossibility of creeping in those portions of the web that constitute thepackage itself. The portion of the web extending in unfolded conditionfrom the package to the rolls of the typewriter is short, so that theopportunity for creeping is limited, and owing to the snugly foldedarrangement of the plies and the pressure of said plies together by thedevices of the typewriting machine, the possibility of creeping ordisalinement becomes negligible, so that the forms are always inregister or in their relative places when at the printing point of thetypewriter.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.

Having thus described my invention, I claim:

l. A web pack of work-sheets adapted for use in manifolding, said packcomprising a plurality of separate strips of extensive length superposedone upon another, longitudinally folded and nested in snug relation onewithin another, and zigzag crossfolded into compact form.
